Role of the amino terminal RHAU-specific motif in the recognition and resolution of guanine quadruplex-RNA by the DEAH-box RNA helicase RHAU [PDF]

, 2017
Under physiological conditions, guanine-rich sequences of DNA and RNA can adopt stable and atypical four-stranded helical structures called G-quadruplexes (G4).

Family‐level specialization in protein domain insertion architectures

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Domain insertion creates architectures where one domain interrupts another's sequence. Analysis across 2.7 million classified domains reveals that insertions occur in 20% of multidomain proteins, with 331 families exhibiting consistent architectural roles: 162 function exclusively as hosts, while 169 exclusively serve as inserted modules, such

Degradation of Hypomodified tRNA\u3csub\u3ei\u3c/sub\u3e\u3csup\u3eMet\u3c/sup\u3e in vivo Involves RNA-dependent ATPase Activity of the DExH Helicase Mtr4p [PDF]

, 2008
Effective turnover of many incorrectly processed RNAs in yeast, including hypomodified tRNAi Met, requires the TRAMP complex, which appends a short poly(A) tail to RNA designated for decay. The poly(A) tail stimulates degradation by the exosome.

SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

The FEBS Journal, Volume 293, Issue 9, Page 2579-2598, May 2026.
The SARS‐CoV‐2 nucleocapsid (N) protein is not only the specific viral RNA packaging protein, but also acts as an RNA chaperone, facilitating RNA folding. We show that it facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone.

The Role of Histone Modifications in Plant Priming and Their Analysis by Chromatin Immunoprecipitation

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Plants are frequently exposed to adverse conditions. Priming, also known as acclimation or hardening, induces stress memory and prepares plants for future challenges by activating defense and protective mechanisms. For this reason, priming is an effective means to maintain plant yield in the face of climate change. Memory behind the priming is

Identification and characterisation of transcriptional regulatory proteins that modulate estrogen receptor α activity

, 2009
Breast cancer is the most common malignancy in women in the Western world, accounting for 18% of all female cancers. Two-thirds of breast cancers express Estrogen receptor-α (ERα) and ERα is a predictive and positive prognostic marker.

Caspase-mediated DDX46 cleavage unchains antiviral immunity

mBio
DEAD/H-box RNA helicases are critical regulators of host antiviral innate immunity. In this study, we utilized an RNA-binding protein knockout sub-library to identify DDX46, a member of the DEAD/H-box RNA helicase family, as an essential proviral host ...

Innate Immunity and Microbial Recognition in Reproduction: From Barrier Defense to Maternal–Fetal Tolerance

The FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Graphical abstract illustrating the barrier defense–tolerance framework of reproductive innate immunity. Across the female and male reproductive tracts and the maternal–fetal interface, epithelial barriers, innate sensors, immune cells, and microbial signals are integrated to preserve reproductive homeostasis.

Helicase protein DDX11 as a novel antiviral factor promoting RIG-I-MAVS-mediated signaling pathway

mBio
Type Ι interferon (IFN) production mediated by retinoic acid-inducible gene 1 (RIG-I) and mitochondrial antiviral signaling protein (MAVS) is essential for antiviral innate immune responses.
